Features: It is a timer relay module with high precision, stable and reliable performance. There is a wide range of delay time that you can set by connecting the S1 to S5 welding joints.12V DC input voltage, and the load capacity is up to 30A250VAC or 30A30VDC. This timer switch module supports power supply reverse input protection.Widelyused on timer operating equipment, household electrical appliances, lighting delay modification, factory equipment, time delay control, etc. Specifications: Time Delay: 0Seconds~60Minutes(adjustable) Time Delay Error: <2%Load Capacity: 30A 250VAC/30A 30VDC Size: 82*35mm / 3.22*1.37" Quantity: 1 Instruction: 1, Solder S1~S5 welding joints in different ways according to the delay time table to set delay time.2, When none joints are soldered, trigger to connect, and trigger again to disconnect.3, Control signal is trigger type signal, after trigger, time delay will not be affected if withdraw or maintain signal.4, If trigger again during delay time, delay time will be restarted.5, If trigger terminals were connected directly without a trigger button, each time powering on the board is equal to pressing trigger button once. Function 1: Power on to connect load, and disconnect after delay time. Method: Connect trigger terminals directly. Function 2: Power on (trigger disconnect) to enter time delay mode, and connect after delay time. Method: Connect trigger terminals directly, solder S6 joints.Package Includes: 1 x Timer Relay Module .
